Hi i am facing one issue,

In the action before webbook i am doing a transform due to which i am getting the following array of users  
"payload": {  
"\_value": [  
"xyz",  
"abc"  
]  
}  
i want to pass this payload.\_value to the rest api with out any modification.  
REST API expects user list "User": ["user1", "user2"]

on using

"body" : "{  
"User": "{{ctx.payload.\_value}}"  
}"  
it is going as "body": "{"User": "{0=xyz, 1=abc}" }"

can you help me in fixing this?

Hey,

check out the `toJson` directive of mustache scripting. See [https://www.elastic.co/guide/en/elasticsearch/reference/5.2/search-template.html#\_converting\_parameters\_to\_json](https://www.elastic.co/guide/en/elasticsearch/reference/5.2/search-template.html#_converting_parameters_to_json)
